another IKEA JANSJÖ modding for my workshop - but help needed

I ordered xgp3 high cri from led-tech.de but ran into trouble with the stock driver.
cree xpg3 constantly burning out (butchered thread)

So for now I am using these because that’s what I had:

My stock psu from 2011 has 4V 750ma.
I’m using another psu because I have 3 lamps in parallel.

On another series of lights I am using a MeanWell LCM60 with MySensors Dimmer at the drivers pwm input.
It looks you are going for a more lightweight setup for shop use.
